were discovered in and near Morrison by Arthur Lakes. The majority of these fossils were shipped to O.C. Marsh at Yale's Peabody Museum of Natural History in New Haven, Connecticut. These finds from the Morrison area figured in the 19th century "Bone Wars" between rival paleontologists Edward Drinker Cope and Othniel Charles Marsh.
Eventually, the late Jurassic section of sedimentary rock excavated by Lakes was dubbed the Morrison Formation in honor of the town.
The Morrison Natural History Museum in Morrison houses and displays some fossils found by Lakes and has begun reworking Lakes' original digs. In 2006, the MNHM reported rare adult

Cretaceous age dinosaur tracks and one of Lakes' histroic dig sites can still be viewed on what is now known as Dinosaur Ridge east of Morrison.
